The Symbolism of Water Many works of literature use symbols to represent abstract ideas. One symbol that is commonly used is water. Water is a viable symbol because it is versatile. It can be used to represent many different ideals because water in itself is ever changing.
any milk or milk by-products, such as cheeses, ice cream, butter, etc is considered dairy. Soy milk is okay, as is rice milk. Eggs are considered dairy, but as they don't come from a cow, I am not sure that would be included in your excluding dairy--same goes for goat's milk and it's by-products.
Eggs are considered by most people to be a dairy product. However, they are not dairy in the traditional sense. A true dairy product is made by the mammary glads of a mammal. Eggs do not fit this definition, however they are an animal byproduct, which is why they are are lumped into the same group as dairy products.
